Title: Radio printing telegraph systems
IPC: H04L1/08
Filed: 1931-09-17
Abstract: 389,504. Wireless signalling. INTERNATIONAL COMMUNICATIONS LABORATORIES, Inc., 67, Broad Street, and HALLDEN, F. G., 8622, 252nd Street, Bellerose, Long Island, both in New York, U.S.A. Sept. 17, 1931, No. 26048. [Class 40 (v).] Relates to systems for the elimination of the effect of atmospherics and in which each signal element is repeated at predetermined intervals for a predetermined number of times and comprises apparatus whereby each element is successively transferred through a series of storage relays between each repetition. The transmitter described comprises a five-element code sender 1, the circuits of one of the five contacts 6 being described, a three-channel multiplex rotary distributer X, shown developed, and a transmitting relay 8 controlling the radio transmitter 109. It also comprises a chain of relays D .. M along which the impulse corresponding to each code element is propagated by means of transfer relays A, B, C associated with the segments 10, 17, and 18 respectively of the distributer X, the relays D, I, and M being associated with the fifth pulse segments 7, 19, and 20 respectively, to co-operate with the sending relay 8 for three separate transmissions of the same code element. The first signal due to the closure of contact 6 of the code sender 1 occurs when brush 5<1> of the distributer reaches the fifth pulse segment 7 of the third channel 46, establishing a circuit through the transmitting relay 8 and relay D, which locks up through contacts 9, 12. When the brush 5<1> reaches the segment 10, the relay A and stepping magnet 3 of the sender 1 are energized, the former making contact 11 and then breaking contact 12. This energizes a winding of relay E through contact 14 of relay D and then restores the latter, the impulse being now transferred to relay E which locks up over contact 60 of relay B. In a similar way, when brush 5<1>, in its second revolution, reaches segment 17 the impulse is transferred by relay B to relay F. On its third revolution when brush 5<1> reaches segment 18, relay C transfers the impulse from relay F to relay G, and on reaching segment 10 relay A transfers the impulse from relay G to relay H. When the brush 5<1> reaches segment 19 on the fourth revolution, relay I and transmitting relay 8 are energized, the latter to transmit the first repetition of the original impulse. On reaching segment 17 the brush 5<1> operates relay B to transfer the impulse from relay I to relay J and release relays H and I. The impulse is then progressively transferred through relays K, L, and M as before, and then when brush 5<1> reaches segment 20 transmitting relay 8 is energized for the third time to give a third and final transmission of the signal. Relay M is restored when brush 5<1> reaches segment 18. The receiver, Fig. 3 (not shown), is constituted by a similar distributer and bank of storing and transfer relays, the arrangement being such that the printer is not operated unless all the three transmitted signals are received and at the correct instant.
